(TSX / STATS) -- Michigan coach Jim Harbaugh said starting quarterback Wilton Speight would not be available this week if the Wolverines had a game, adding that the hit that knocked him out last week was "egregious."

"If I had a stronger word to use, I would use it," Harbaugh said at his Monday press conference.

Speight sustained a head injury in the first quarter of a 28-10 win at Purdue on Saturday. Senior John O'Korn came in and completed 18 of 26 passes for 270 yards and a touchdown.
